This bracelet of gilded or gold-plated silver comprises a hammered silver sub-structure that is decorated around both sides with a band of tightly-curled filigree, and on the outer surface with dozens of rows of spikes.
The bracelet has a one-third opening construction, with a hinge and an opening screw mechanism.
Gilded silver jewellery from Yemen is unusual but not unknown. Related examples (also gilded) are illustrated in Geoffroy-Schneiter (2011, p. 31). Wealthier clients would ask local goldsmiths to gild their silver jewellery for them.
The example here is in fine, wearable condition. There are no losses and the gilded is still intact and has softened in time to a pleasing, subtle hue.
